Abstract: A portable light treatment device is capable of delivering the illumination which is sufficient in amount but mild to the subject's eyes for assuring effective light treatment without unduly annoying the subject.  The device has a surface illuminating unit having an effective surface region of at least 15 cm2 which emits a visible diffused light of reduced luminance variation. The light is selected to give an illuminance of at least 2000 LUX measured at an eye position of the subject. A mount member is provided to mount the surface illuminating unit to a portion adjacent to eyes of the subject to direct the diffused light to the eyes of the subject. Thus arranged portable illumination device has an advantage of delivering sufficient amount of the light to the subject's eyes without dazzling the subject and therefore administering effective treatment without imposing severe restrictions to the subject's daily activities. Preferably, the diffused light is selected to have an average luminance of from 1,000 to 4,000 cd/m2 and have a maximum luminance of less than 6,000 cd/m2 in order to minimize the dazzling effect. Further, the ratio of a maximum to minimum luminance appearing in the effective surface region is selected to be less than 2.5 and difference in luminance between any two points spaced by 2 mm is less than 100 cd/m2 in order to further minimize the dazzling effect.

Abstract: A laser system for imaging graphic-arts constructions avoids the need to demagnify a divergent beam by using the output of a semiconductor or diode laser to optically pump a laser crystal, which itself emits laser radiation with substantially less beam divergence.  A preferred implementation utilizes, as a pumping source, at least one laser device that emits in the IR, and preferably near-IR region, to image ablative or transfer-type printing members.  The output of the pumping source is provided to the laser crystal via a focusing lens arrangement.  The output of the laser crystal, in turn, is focused onto the surface of a recording medium to perform the imaging function.  Crystal excitation and decay times are minimized by continuously maintaining the pumping source at a bias power level, which keeps the crystal at a continuous, baseline power level just short of lasing or imaging; and then selectively and intermittently increasing power to the pumping source to cause the crystal to lase (or lase at higher power) in an imagewise pattern.  By selectively varying the pulse width within certain limits, it is possible to obtain image dots of different sizes while retaining a round dot shape.

Abstract: The present invention relates to systems for sharing idle workstation computers that are connected together through a network and shared file system. More particularly, a user of a local host workstation may submit jobs for execution on remote workstations. The systems of the present invention select a remote host that is idle in accordance with a decentralized scheduling scheme and then continuously monitor the activity of the remote host on which the job is executing. If the system detects certain activity on the remote host by one of the remote host's primary users, the execution of the job is immediately suspended to prevent inconvenience to the primary users. The system also suspends job execution if the remote host's load average gets too high. Either way, the suspended job is migrated by selecting another idle remote workstation to resume execution of thesuspended job (from the point in time at which the last checkpoint occurred).

Abstract: A system for motion control in which an application is developed that is independent from the actual motion control hardware used to implement the system. The system comprises a software system that employs an application programming interface comprising component functions and a service provider interface comprising driver functions. A  system programmer writes an application that calls the component functions. Code associated with the component functions relates these functions to the driver functions. A hardware designer writes driver code that implements the driver functions on a given motion control hardware product. The driver functions are separated into core and extended driver functions. All software drivers implement the core driver functions, while the software drivers need not contain code for implementing the extended driver functions. If the software driver does not contain code to implement an extended driver function, the functionality of the extended driver function is obtained through a combination of core driver functions. The system programmer may also select one or more streams that allow the control commands to be communicated to, and response data to be communicated from, motion control hardware.

Abstract: A thermoelectric cold junction compensator connector module, for use with a thermoelectric device such as a thermistor, thermocouple, or resistance-temperature device, has within a housing a cold junction compensator circuit which has means for linearization of voltage output of the circuit relative to input to the circuit. Preferably the circuit also includes potentiometer means for adjustment of at least one parameter of the circuit, and means for adjustment of its voltage output to correspond to degrees Centigrade and degrees Fahrenheit. In a preferred form there are included within the housing a pair of input terminals shielded by ferrite material against stray electromagnetic induction signals, a printed circuit board which comprises a cold junction compensation circuit, a signal linearization circuit, a converter/amplifier circuit, and a circuit for selectively providing a degree Centigrade and degree Fahrenheit output, a battery power supply, and a battery status indicator with means for bringing it into and out of operation, a plurality of potentiometers for preliminary setting up of the circuits, an on-off switching means for the powered circuits, and output terminal means for connection to, for example, a voltmeter or a voltage recording device. The compact body may have a base portion on which the circuits and other items are mounted, and one or more removable cover portions securable on the base portion. Further, a thermocouple voltage-to-analog connector is in the form of a compact hand-held module which contains all the components and power supplies for converting an input of thermocouple output voltage to a linear and cold-junction-compensated analog output. A particularly advantageous feature is that an on-board analog-to-digital converter only calculates and provides the linearity correction, necessary for the specific thermocouple at a specific temperature, in the form of a pulse width modulation signal output, so that about 95 % of the analog output is derived from the output of a thermocouple amplifier and temperature sensor, and only 5 % of the remaining signal is derived from the on-board micro-processor.
